CAN-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 371,484, dated Qotooer 11, 1887.

Application filed August 17, 1887. Serial No. 247,149. (No model.)

To all whom it may concern.-

Be it known that we, EDWIN E. ANGELL, of Maiden, Massachusetts, and CHARLES E. KEN- DALL, of Newton, Massachusetts, have invented jointly new and useful Improvements in Can-Making Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of our invention is to provide a IO simple and effective machine by which canbodies can be successively brought between automaticallyoperating headers, and when headed be automatically discharged from the conveying cylinder or carrier. The special :5 heading mechanism which we prefer to employ is embraced by our application No. 246,925, filed August 15, 1887; and our invention consists in the special combinations embraced by the claims appended to this specification.

In the drawings, Figure l is an end elevation of our improved can-machine. Fig. 2 is a side elevation of the same, and Fig. 3 a vertical central section thereof.

A is the supporting-frame of the machine. The cylindrical can-bodies, in theform of openended sheet-metal shells, come continuously forward by gravitation in the inclined trough B. (Seen broken away at the left of Fig. 2 and the right of Fig. 3.) At the lower end of 0 this trough the carrying-wheel O, fixed on shaft D, revolves with an intermittent motion. Its periphery is furnished with a succession of semicircular pockets, 0, each of which receives from the trough B one of the can-bodies and carries it upwardly, as best shown in Fig. 3. Curved guide-plates G, constituting a prolongation of the sides of trough B, insure the correct position of the can-bodies, and acurved spring, 9, acts as a guard against their dis- 0 placement radially.

E is the driving-shaft of the machine, driven by belt and pulleys. (Not shown.)

F F are grooved cams on shaft E to receive terminal studs on levers L, pivoted at Z, by

which the headers H are caused to slide with their splined shafts h at the proper moment toward and from each other, as best shown in Fig 1. The shafts h are provided with fixed collars h and If and sliding collars h and between the latter collars and the collars if are placed the stiff spiral springs J. The pins L at the upper ends of the levers L are entered between the sliding collars h and the fixed collars h, the said springs yielding when necessary as the shafts hare rcciprocated to 210- 5 5 commodate slight variations which may occur in the lengths of the bodies of the cans which are being headed. Thus if a can-body is a little longer than usual the can would be liable to be spoiled in the operation of setting the heads by the headers operated from the uniformly-moving levers L were it not for the elasticity afforded by the springs J and sliding collars it, which form yielding connections between the levers L and the shafts h.

The internal construction of the headers and the details of their operation are set forth in our formerapplication on heading mechanism, already referred to, and need not be explained here. Jaws within the headers are worked simultaneously to hold and release the heads by means of projecting arms 'I, engaging with pivoted levers t, actuated by cams X on the main shaft.

Intermittent rotation of the carryingwheel O is required to present one of the can-bodies in exact position between the headers at the instant when they are ready to move toward each other, each carrying a head to be applied to the can. The means we have devised for this purpose are best shown in Fig. 2. The shaft D of this wheel 0 has fixed upon it a ratchet-wheel, (Z, actuated by a hooked pawl, i, carried on a longitudinally-reciprocating bar, I, which is moved vertically in suitable guides by a pivoted lever, K. This lever is operated by a cam, k, on the main shaft E, and it acts on the vertical bar I through a friction-roller. A suitable spring keeps the hook of the pawlt' constantly engaged with the ratchet-teeth. We lock the wheel 0 tomporarily in position while the heads are being applied by suitable devices, preferably by a pivoted lever, M, Fig. 1, entering lateral notches c in the wheel and held therein by a 5 spring, at. A forked lever, N, Fig. 3, e11- gages at one end with the lever M and has at its other end a projecting stud acted upon by a cam, n, on the .shaft E to throw back the lever M positively at the right time.

We have provided means for holding the can-body firmly in the pocket 0 while being headed, as best shown in Fig. 3. Semicircular clamps, consisting, preferably, of two parallel plates, 0, fitting the periphery of the canbody near each of its ends and carried on a pivoted lever, 0, hold the body steadily, so that when the heads are applied, as at P, Fig. 3, their flanges will overlap the ends of the body. and adhere'frictionally thereon. The

clamp is shown as operated by a pivoted lever,

Q, and connecting-rod q, actuated by a cam, R, on shaft E and a retracting-spring, r.

The clamps release the can as soon as head ed and the movement of wheel 0 brings another body into position. Inclined plates or guides S then dislodge the headed can and cause it to roll forward automatically for the next'operation. These guides S are shown in Fig. 1 as turned up edgcwise from lateral plates 8 fixedto the standards of the frame A.

We claim as our joint invention 1. The combination, with the headers Hand the lengthwise-movable shafts h, by which they are carried, of levers for reciprocating said shafts and yielding connections between the said levers and shafts, substantially as set forth.

2. The combination, with the headers H and their shafts h, provided with the fixed collars h and h and the movable collars h, of the springs J between the said collars h and h,

and the levers L, for reciprocating the said shafts, substantially as set forth.

3. The combination, with the headers H and their shafts h, having the fixed collars h and h and the movable collars h of the springs J, the leversL, having pins L, the cams F, andthe driving-shaft E, substantially as set forth. l

4. The combinatiomwith the carrying-wheel 0, having the notches c, of the lever M, the spring m, the forked lever N, the cam n, and the shaft E, substantially as set forth.

5. The combination, with the lever 0 and the semicircular clamps 0, carried thereby, of the wheel 0, the rodq, the lever Q, the cam R,

and the shaft E, substantially as set forth.

6. The combination, with the carrying wheel or carrier C, of the-inclined feeding-trough B, having the guides G, the clamping device for holding the cans while being headed, and the stationary dislodging-guides S, for removing the headed cans from the said wheel, substantially as set forth. v

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 13th day of August, A. D. 1887.
